Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a battery compartment structure of a multi-rotor unmanned aerial vehicle. Background Art

[0002] There are a wide variety of multi-rotor unmanned aerial vehicles on the market now, and the designs of battery compartments are uneven. Most of the battery compartment designs only consider the fastening and heat dissipation of the battery. However, when the unmanned aerial vehicle has a crash accident, the battery cannot cut off the main power supply, and there is also a problem of battery short circuit and fire caused by structural damage, resulting in the destruction of aerial photography materials and even causing a fire. Therefore, it is necessary to redefine the battery compartment structure of the unmanned aerial vehicle to provide safety protection for it. Summary of the Utility Model

[0003] The utility model provides a battery compartment structure of a multi-rotor unmanned aerial vehicle. Its floating tray provides a supporting force for the battery under the action of an elastic support body, and forms a protective armor outside the battery, avoiding broken fragments piercing the battery under severe impact, and the problem of internal short circuit caused by the battery being deformed by impact, thereby improving the safety of the battery and avoiding the losses caused by battery fire.

[0004] In order to achieve the above purpose, the utility model provides the following technical solution: A battery compartment structure of a multi-rotor unmanned aerial vehicle, which includes: a buffer cavity, the buffer cavity is fixedly connected to the main body of the unmanned aerial vehicle, and an opening is provided on one side of the buffer cavity, and a buffer cover is provided at the opening; floating trays are respectively provided on the inner walls of the buffer cavity and the buffer cover, and each floating tray is respectively connected to the inner walls of the buffer cavity and the buffer cover through an elastic support body; slots are respectively provided at the joint parts of the buffer cavity and the buffer cover, and the two slots form a power line channel; the buffer cover is connected to the opening of the buffer cavity through a locking mechanism.

[0005] Preferably, grid-shaped reinforcing ribs are distributed on the inner side walls of the buffer cavity and the buffer cover, each elastic support body is respectively provided with a rubber block, each rubber block is embedded in the grid space formed by the corresponding reinforcing rib, and a through hole is provided in the grid space, and a fixing screw passing through the through hole and threadedly matched with the rubber block is further included.

[0006] Preferably, a number of foam pads are further included, and each foam pad is respectively embedded in the remaining grid space formed by the reinforcing ribs.

[0007] Preferably, arc-shaped guiding surfaces that are turned outwards and rolled are respectively provided at both ends of the floating tray on the side wall of the buffer cavity.

[0008] Preferably, the locking mechanism includes a pair of lock rods passing through the buffer cover. A lock hook is provided at one end of each lock rod corresponding to the inside of the buffer cover, and an unlocking plate is provided at the end of each lock rod outside the buffer cover. Moreover, extraction plates are respectively and spacedly provided outside the buffer cover corresponding to the outside of each unlocking plate. A spring is provided between the unlocking plate and the extraction plate; a lock groove corresponding to the lock hook is provided on the inner side wall of the buffer cavity.

[0009] The beneficial effects of the present utility model are as follows: The buffer cavity and the buffer cover form a cabin structure for accommodating the battery of the drone. The suspension tray therein provides a supporting force for the battery under the action of the elastic support body, and forms a protective armor outside the battery through the suspension tray. A buffer space is formed between the suspension tray and the inner wall of the cabin, avoiding the problem that broken fragments pierce the battery and the internal short circuit caused by the deformation of the battery due to impact under severe impact, thereby improving the safety of the battery and avoiding the losses caused by battery fire. The grid-shaped reinforcing ribs effectively improve the self-strength of the buffer cavity and the buffer cover, and at the same time use the grid space to position and fix the elastic support body, providing the stability of the suspension tray. When the impact force is too large and causes the buffer cavity and the buffer cover to crack, the foam pads in each grid space support and isolate the suspension tray, preventing the broken fragments from piercing the suspension tray and affecting the battery safety. The arc-shaped guiding surface is beneficial to the installation and disassembly of the battery. Even after the buffer cavity is slightly deformed, the battery will not be stuck at the edge position, thus ensuring that the battery can be taken out smoothly. The buffer cover is positioned and locked with the buffer cavity by the lock hook, and the lock hook is disengaged from the lock groove by pressing the unlocking plate during unlocking.

[0017] According to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a battery compartment structure of a multi-rotor drone includes: a buffer cavity 1, which is fixedly connected to the main body of the drone, and an opening is provided on one side of the buffer cavity 1, and a buffer cover 2 is provided at the opening; suspension trays 3 are respectively provided on the inner walls of the buffer cavity 1 and the buffer cover 2, and each suspension tray 3 is respectively connected to the inner walls of the buffer cavity 1 and the buffer cover 2 through an elastic support 4; slots are respectively provided at the joint of the buffer cavity 1 and the buffer cover 2, and the two slots form a power cord channel 5; the buffer cover 2 is connected to the opening of the buffer cavity 1 through a locking mechanism.

[0018] In this structure, the buffer cavity 1 and the buffer cover 2 form a cabin structure for accommodating the battery of the drone. The suspension tray 3 therein provides a supporting force for the battery under the action of the elastic support 4. The elastic support 4 is realized by a rubber column or a spring. Therefore, it can provide a buffering force and a supporting force for the suspension tray 3. At the same time, a protective armor is formed outside the battery through the suspension tray 3, and a buffer space is also formed between the suspension tray 3 and the inner wall of the cabin, avoiding the problem that broken fragments pierce the battery under severe impact and the internal short circuit problem caused by the deformation of the battery due to impact, thereby improving the safety of the battery and avoiding the loss caused by battery fire.

And a through hole is provided in the lattice space. A fixing screw that penetrates the through hole and is threadedly engaged with the rubber block 7 is also included.

[0020] With this setting, the grid-shaped reinforcing rib 6 effectively improves the self-strength of the buffer cavity 1 and the buffer cover 2. At the same time, the grid space is used to position and fix the elastic support 4, providing the stability of the floating tray 3.

[0021] It also includes a number of foam pads 8, and each of the foam pads 8 is respectively embedded in the empty grid spaces formed by the reinforcing ribs 6.

[0022] When the impact force is too large and causes the buffer cavity 1 and the buffer cover 2 to rupture, the foam pads 8 in each grid space support and isolate the floating tray, preventing the broken fragments from piercing the floating tray 3 and affecting the battery safety.

[0023] Both ends of the floating tray 3 located on the side wall of the buffer cavity 1 are respectively provided with arc-shaped guiding surfaces 9 that are turned outwards and rolled up. The arc-shaped guiding surfaces 9 are beneficial to the installation and disassembly of the battery. Even after the buffer cavity 1 is slightly deformed, the battery will not be stuck at the edge position, thus ensuring that the battery can be taken out smoothly.

[0024] The locking mechanism includes a pair of lock rods 10 that penetrate through the buffer cover 2. One end of the lock rod 10 corresponding to the inside of the buffer cover 2 is provided with a lock hook 12, and one end of the lock rod 10 located outside the buffer cover 2 is provided with an unlocking plate 11. And extraction plates 14 are respectively and spaced outside the buffer cover 2 corresponding to the outside of each unlocking plate 11. A spring is arranged between the unlocking plate 11 and the extraction plate 14; a lock groove 13 corresponding to the lock hook 12 is arranged on the inner side wall of the buffer cavity 1.

[0025] With this setting, the buffer cover 2 is positioned and locked with the buffer cavity 1 by the lock hook 12, and the lock hook 12 is disengaged from the lock groove 13 by pressing the unlocking plate 11 during unlocking.
